Thanks for the nice comments, everyone.
E350 - I sooo appreciate someone with honest and direct advice (and a sometimes differing view of things
).
The engine in this rig isn't the original. According to the previous owner, it's a crate engine that has now 30,000+ miles on it. He could come up with the receipt for the exchange, but not with the paperwork for the engine. According to a few people that looked at it, it is indeed the 351 (don't ask me how they know...), but I wouldn't know how to tell.
I think I'll go ahead and figure out more details about the engine before I start asking more specific questions as I don't want to look like an engine savage - which I am, though
